Hi, I am looking to run a script which calls other functions from other scripts. Such as in script 1 I may have function f1 which then calls functions f2, f3, f4 which are found in script 3 and then f4 also calls function f6 which can be found in script 3 etc. What I am looking to do is to create a text file that reports any errors or warnings that come about while running this script, and then also reporting which function and script that error/warning occurs. Any help would be greatly appreciated.
